Description
Technical field
This disclosure relates to the method for executing the wireless device auxiliary switching from source access node to Target Access Node
And equipment.
Background technique
Standard of the third generation cooperative partner program (3GPP) to Universal Mobile Telecommunications System (UMTS) and long term evolution (LTE)
Change and is responsible for.The general land that work of the 3GPP in terms of LTE is also referred to as evolution accesses net (E-UTRAN).LTE be for realizing
The technology of the packet-based communication of high speed, can in the downlink with all reach high data rate in uplink.In order to prop up
Hold high data rate, LTE considers the system bandwidth of 20 MHz, or up to 100 MHz are when using carrier wave polymerization
Regiment commander is wide, and LTE will continue evolution.While LTE evolution, cellular technology of new generation is just developed, i.e. the 5th generation system
Unite 5G.Compared with LTE, for 5G task first is that promoting handling capacity and capacity.This is partially by the every carrier wave of increase
Bandwidth and sampling rate obtain.5G further includes being higher than the carrier frequency of 6 GHz using higher carrier frequency.
In UTRAN and E-UTRAN, user equipment (UE) or wireless device are wirelessly connected to radio base station (RBS),
It is commonly known as NodeB(NB in umts), and the commonly known as NodeB(eNodeB or eNB of evolution in LTE).Nothing
Line electricity base station (RBS), access node (AN) or access point (AP) are for that can transmit radio signal to UE and receive by UE
The generic term of the radio network node of the signal of transmission.In wireless lan (wlan) system, wireless device is also by table
It is shown as work station (STA).
Following communication network, which will be largely expected, uses advanced antenna system.Using such antenna, letter
It number will be transmitted in narrow transmission beam, to increase the signal strength on certain directions, and/or be reduced dry on other directions
It disturbs.Dependence and high frequency to Wave beam forming make that reliable radio link is maintained to be challenging.Narrow beam may
Soon lose-especially when being combined with bad diffraction characteristic.Therefore, the high frequency radio access based on Wave beam forming
The loss that technology is easier by the suddenly change in link-quality or even to cover is influenced, this, which may cause, significantly prolongs
Slow and signaling can be restored simultaneously to find covering again until wireless device.
Unrelated with the presence of the UE in system or position in LTE, some downlink reference signals are to be always on
(always-on) mode is simultaneously broadcasted on full bandwidth.These signals are referred to as cell specific reference signal (CRS).It connects
The user equipment (UE) for receiving reference signal can measure the quality of neighbor cell for mobility purpose.It is logical in such Future cellular
In communication network, in all each transmission beams using reference signal it is such continuously transmit to consume can be used for data
Resource, and a large amount of interference are generated in neighbor cell.Continuously transmit the high energy consumption also resulted in radio access node.
For report an option of the measurement (also referred to as mobility reference signal measure) from UE back to NW be using
RRC signaling.Information is grouped together in L3 rank, and long reported lengths can be supported, and the long reported lengths allow to transmit and permitted
The signal strength or the relevant information of quality of the alternative link mark and its estimation that more detect.Receiving these measurement reports
When, network can make switching and determine or keep in the cell or be moved into identical frequency, another frequency for UE
Another cell in rate and/or RAT.Link conversion determines can be then by NW consideration link-quality and network state parameters
Combination is to make.
It is based on object however, also studying for another option using non-RRC report disposition radio link
Layer, report based on L1, using uplink synchronisation sequence (USS) are managed, the uplink synchronisation sequence is to carry together
Walk the locally-unique signal of pilot tone and mark.Alternatively, before Physical Random Access Channel (PRACH) can be used in the report based on L1
Leading code.UE can be configured to send USS to target, to indicate the collection of such as candidate's DL wave beam by the USS sequence of pre-configuration
Best DL wave beam in conjunction.UE is configured for executing the mobility measurements of multiple candidate beams also, is detecting most high-amplitude wave
Shu Shi；It should be directly accessed the node that it is derived from.This be by send its uplink (UL) resource (time/frequency gap,
Sequence) USS associated with downlink (DL) wave beam carry out；The association is pre-configured by network.Receive AN(for example
Target AN) it is that USS detection retains UL resource in advance, this allows to report with the smallest time delay to transmit.Receiving USS report
When, AN(such as target AN) new service link can be signaled in DL, with allow UE synchronization parameter update with
And other possible configuration changes.This method based on L1 be wherein service link SINR can due to masking
(shadowing) the faster mode of object beam is accessed in the scene of rapid decrease, and in terms of robustness and time delay
Promotion prepare, this is due to the fact that: report is sent directly to target by UE, and in the method based on RRC UE need
Measurement is sent to source, wait the decision from source and finally from the service link being likely to be under severe radio condition
RRC connection is received to reconfigure.
Measurement report based on RRC allows to transmit metrical information reliable, abundant from UE to network, but usually with suitable
Big signaling overheads and potential high time delay.Come only for mobility decision using RRC signaling, it, may be for 5G such as in LTE
In new radio (NR) contemplated by (high-gain Wave beam forming is such as just used in upper frequency as UE in some scenes
When) lead to the problem of.There, may be declined quickly by the link-quality that wave beam provides, this is because when disposing LTE in frequency
The narrow covering of the strong shadowing effect and wave beam that are not present.RRC signaling can therefore be unsuitable for wherein link-quality most
Scene in the system of the Wave beam forming reduced rapidly except good overlay area.Alternate ways based on USS report may be
It is led to the problem of in other scenes, and complexity and resource disadvantage may be left.In the report based on USS, UE is only capable of passing every time
Pass single link report.To which wave beam conversion or mobile process effectively become to be controlled by UE, this is because most from UE
Good link detecting and report have determined Target Link.Accordingly, there exist there is the needs for promoting measurement report, to support mobility mistake

Best DL wave beam in set.
In the report based on RRC, UE is configured to measure so-called mobility reference signal, and in certain pre-configurations
When the triggering of event (for example, served beams are lower than first threshold, and neighbour's wave beam is higher than second threshold), UE is via foundation
RRC connects the RRC measurement report message that including synthesis, reliable metrical information is sent to one or more service source AN.Base
In this, AN, or determined more precisely, managing ambulant network function and can make valid mobility, because of report
